VII International Workshop on Collapse Calderas

VII International Workshop on Collapse Calderas

Toba Caldera, Sumatra, Indonesia

Workshop: 21st to 27th September, 2018

Workshop Outline

The workshop, like previous meetings, will be a venue to discuss many diﬀerent aspects of calderas, their physical setting, associated magmatic processes, eruption dynamics, impacts of eruptions, hazards associated with caldera volcanism and their mitigation. Taking advantage of Toba’s unique record, resurgence will be a major theme. The workshop will consists of 3 full days of presentations and discussion, and 2.5 full days of ﬁeld-based discussions.

The workshop will be held in charming Tuk Tuk on the eastern edge of Samosir island.Field trips will visit the key sites and outcrops of Samosir Island and Toba caldera. An optional visit to Sinabung Volcano Observatory is available to view the activity there. You will be able to enjoy the traditional Batak culture of Samosir.

Venue

What is the Commission on Collapse Calderas?

The IAVCEI Commission on Collapse Calderas (CCC) was created in March 2008 to have a wider and deeper understanding on calderas. The idea to file for a commission emerged in 2005, during a workshop on Caldera Volcanism, at which the Collapse Calderas Work Group was formed. The CCC includes a wide spectrum of disciplines, such as caldera geology, geophysics, mathematical and analogue modelling, subcaldera magma chamber processes, volcanic hazard and risk management, economic benefits and environmental research. Thus, it promotes interdisciplinary interaction to help solve the many questions regarding the formation of collapse calderas, theri evolution, and affect on society. Successfull workshops have been organized on a regular basis, and have been previously held at Tenerife, Canarias (2005), Mexican Vilcanic Belt (2008), Reunion Island (2010), Bolsena, Italy (2012), Taupo, New Zealand (2014), and Hokkaido, Japan (2016). 50 person attended to the 6th workshop in Hokkaido.

“Millennia of Stratification between Human Life and Volcanoes: strategies for coexistence”. Attention will be on the resilience of human societies to volcanic risk, and volcanic environments perceived as resources.
